My invention has for its object to provide a simple and efficient automobile window regulator construction that may be made at low cost of construction. The invention pertains to that type of window regulators having a rack. to which is connected an arm, the rack ;lation to a supporting means.

The invention may be contained in structures that differ in their details and, to illustrate a practical application of the invention, I have selected a structure embodying the invention asan example of such structures and shall describe it hereinafter. "The structure selected, for purposesof illustration, is shown in the accompanying drawing.

Fig. 1 of the drawing illustrates a slde view of a portion of the window regulator, selected as an example, to which my invention particularly relates. Fig. 2 is a view of a section taken on the plane of the line looking in the direction of the arrows marked 2-2fin Fig. 1. Fig. 3 is a-view of a section taken on the plane of the same line looking in the direction indicated by the arrows marked3-3 in Fig. 1. Fig. 4 illustrates a perspective view of an oscillatable pivot pin for pivotally supporting the rack. Fig. 5 illustrates a perspective view, of the pivot ,pin shown in Fig. 4 and the manner in which it is secured to one of the parts ofthe structure whereby one of the parts is pivotally supported relative to the other of the parts.

As is well known in the type of regulators, one of which has been selected as an example of such constructions, a supporting element for the window regulator is commonly secured to what is termed as the lock board, and in such a position that an oscillatable element having a projecting arm that may be connected to the window, usually at the lower edge of the window, and a sector that may be operated by a pinion that is connected to a crank located in a convenient position on the inside of the automobile, whereby the crank may be readily rotated to produce the desired oscillatory movements in the rack and arm to raise and lower the window to the desired extent. In the form'of constructionshown, the supporting plate 1 is secured to the lock board by suitable screws or bolts that pass through the openings 2, and if desired to a part of the automobile by a bolt or screw that extends through the opening 3. The oscillatable element 8 of the window regulator is provided with a rack i to which is connected the arm 5, the arm 5 having any of the well known means at its outer end for transmitting or transforming its movements into the desired rectilinear movements of the window. If desiredthearm 5 may be formed integral with the rack 4: or it may be secured'thereto by suitable rivets 6. Also, if desired, the rack 4 may be segmental in form or it may be made arcuate. In the form of construction'shown,

the rack 4 is arcuate in form and its ends are connected to an end portion of the arm 5 by means of the rivets 6. The rack 4 and the arm 5 are pivotally supported by means of the pivot member 7 that may be formed from a. solid bar or from sheet metal. Preferably, the pivot member 7 is formed of sheet metal and has a diameter sufficient to form a good hearing surface for withstanding the strains to which it is subjected to in the operation of the window regulator. The pivot member 7 is preferably connected to the oscillatable element 8 and rotates in the supporting element. I.

The pivot member 7 is connected by inserting in an opening 12 formed in the oscillatable are located in radial recesses 11 formed in the window regulator. The pivot member 7 has a flaring flange 9 and the lugs 10 extend diagonally from the body of the pivot member 7 to the flange 9. The cylindrical pivot memher 7 fits tightly the said opening 12 and as the pivot member 7 is driven home the lugs or flanges 10 enter the recesses 11 which securely locks the pivot member 7 to the oscillatable element 8.

The plate 1 is also provided with an opening for receiving the pivot member 7. The opening in the plate or bracket 1 is formed by depressing the metal so as to form a cylindrical flange 13 about the opening. The

2 ips flange 13 extends outward with respect to the interior of the automobile and forms a broad bearing for the pivot member 7. The pivot member 7 is positioned in the flange so that the oscillatable element will bear against the plate and thus form a lateral-bearing as between the oscillatable element and the plate or bracket 1; If desired, the plate maybe stamped to for-m a raised portionv 1 1- which constitutes the lateralbearinglfor the oscillatable element of the window regulator. The side or top of the raised portion being of a sufficient width to cover a substantialportion of the oscillatable element, it forms there -by. broad bearing areas as between the oscillatable element and the plate or bracket 1.

In the form of construction shown, the 'counterbal-ancing spring ofthe window reg- --u l-ator, that is commonly used for counterba lancingat least, the major portion of the weight of the window, so thatin the opera- ?tionof the window regulator substantially the same power or force is used in raising the window that is required to'lower the windowv and thus provides a uniformity of action in rai'sin'g or lowering; the window, is connected ito the oscillatable element. The counterbalaneing spring, in the form of construction I shown, is a-convolute spring and may be connected at either-end, to the oscillatable element,the other end o'fthe spring being anchored-toe part of the construction, suchas to the-plate or bracket '1. Preferably the inner end of the convolute spring is secured f-to the vpivotmember 7 and-the'outer end is sec-uredtothe plate or bracket. The pivot member 7 isprovided with a recess 16. The recess lfi -may be made L-shape or bayonet f-shape. Preferably, in order to provide ,for

, right and left rotation, or desired location of the operating crank with. reference to other parts of the automobile, the recess 16 is 7 formed T-shape. The ends of the 'convolute spring 15 are hooked and the inner end 18 5 is -locatedin the recess 16, the depth of the --recess being suchjasto provide for the width ,er the spring and alsoto-provide, for the engaginglugs '19, that extend towards each ether. The distance between the juxtaposed surface otthe lugs is sufficient to permit the spring to pass between the lugs 19. The dis- "tance between the lugs is, therefore, somewhat greater than the thickness of the spring. Wi l-ion the spring has been inserted in position aboutthe pivot member 7 it is drawn seas to be subjected to a suilici'ent tension as to counterbalance at-least the major portion ofthe' weight of the window and-the outer end of the spring is anchored to theplate or bracket 1. The hooked :end 20 may be hooked over one or the other of the laterally extending lugs or ears 21 according to whether the-window is raised by right or by left hand rotation. Theinitial turn or deformation of the sprlng from normal, in order to sub]ect oscillatable relation, not only by the pivot 1nember7,-but alsoby' thesupporting plate or bracket 1. The plate or bracket 1 is provided"with a recess 23 111 which the pinion that operates on the rack may be located,

"and 'the'plate'orbracket 1 is provided with the "slots'24 that are formed in thewalls of the pinions thatmay be-locatedintherecess 23. The rack 4 is formed a'rcuate and, consequently, as t'is moved, it will passjthrou'gh theIslots 2i and thusbe held in proper pivotal alignment for the m'ents. I p k r I claim: 7
